In the energy sector, real-time systems management requires robust, up-to-date platforms. An organization specializing in wholesale market management solutions faced one of the most complex challenges of the year: migrating its Oracle database from version 11 to 19, ensuring continuity, security, and synchronization with different providers, without affecting daily operations.
The challenge involved not only the technical complexity of the migration, but also the need to ensure that critical applications would function properly in each environment. To achieve this, a phased plan was designed that included adjustments, testing, and migration in development, testing, and production environments.
The solution included:
- Complete migration of all objects in the database, more than 989,849 objects distributed across 21 databases.
- Adjustments and testing in eight applications, ensuring correct operation in each environment.
- Collaborative work with the client and suppliers, ensuring synchronization and minimal disruption.
The results were outstanding:
- Successful migration with minimal impact on operations, avoiding service downtime even during weekends.
- Proper synchronization between environments, ensuring stability and continuity.
- Guaranteed safety and traceability, complying with technical and regulatory standards.
This experience shows how a well-planned and executed strategy can transform critical processes, ensuring operational continuity and reducing risks in highly demanding environments.
